Which components need to be grounded during PV system installation?
It is recommended that in the photovoltaic power generation system, all non-charged metal parts and equipment shells should be grounded, such as photovoltaic modules, photovoltaic module brackets, inverter shells, grid boxes, etc. Photovoltaic modules have prefabricated grounding holes, which can be directly connected in series for protective grounding. The grounding end of the inverter can be directly grounded alone or can be grounded in parallel with the base line of the grid-connected cabinet. 2. After the system is installed, before the trial run, it should be
